Webmethod Error

I have the webmethod below which executes at 'onbeforeunload' event. it gives an error message that I catch to a log file: 'Object reference not set to an instance of an object' . The error happens sometimes. It does not happen all the time. Any known issues with the way I am accessing my session variables that I should be warned about? Please help? The error happens only on production and not during debbuging. I am setting those session variables at login, so I know for sure there is a value stored in those variables.

I have been struggling to get my jquery call to a webmethod to work. I am being bounced by the server with a "401 Unauthorized" response. I must have an incorrect setting in the web.config or somewhere else that would be preventing a successful call.

When I enable Failed Request Tracing Rules and view the log output I am supposing that the actual problem is in the 2nd call where there are 2 backslashes before the actual filename in the specified path:

A couple of days ago I started getting an unusual behavior when compiling Website projects. I have referenced class libraries added to my bin folder that are also correctely referenced in using statements in my aspx.cs code behind. When I compile, I get the

Error4The type or namespace name 'CommonClassLibrary' could not be found (are you missing a using directive or an assembly reference?)C:\Dev\Fiscal_Portal\Implementation\FMS Portal Site_new\App_Code\BLL\DataTables.cs17C:\...\FMS Portal Site_new\

The type or namespace name 'CommonClassLibrary' could not be found (are you missing a using directive or an assembly reference?)

error message that would typically be received when the dll has not been added as a reference or added in a using statement.

I am using VIsual Web Developer and downloaded the small business application to use as a starting point to help my wife get a website up for her small business. When I load the application, I can F5 and it runs fine but as soon as I make any modification to the app and hit F5, I get the HTTP Error 403 - Forbidden when it tries to show the website.

I notice a pop up that occurs when I run that allows me to choose the link for my app and it displays correctly (I close the webpage that has the error on it).

This seems like a pain, is there a setting I'm missing - I would think that this should "just work".

When I try to updated or insert a record in my User table I am getting an error that does not make sense to me and I cannot figure out what is wrong.

Also, when I try to insert a new record I get a validation error saying that the Id is required. However it is an identity field in the db so it should not be necessary to send it to the server.

Could you please shed some light?

Server Error in '/' Application.

Value of member 'ID' of an object of type 'Ref' changed.A member defining the identity of the object cannot be changed.Consider adding a new object with new identity and deleting the existing one instead.

I get this error whenever I attempt to update an entry. Even an entry that has had nothing altered. I have tried to circumvent it but I think it must be a simple oversight. How could I have caused an ID update using the Edit.aspx page of dynamic data? Thank you in advance for the help!

We have an applicaiton that was converted to the new framework using the wizard in Visual Studio 2008. When we install the applicaiton in production and change the iis settings to use the 2.0 framework we start to see these errors in the event viewer on the web servers.

We are using SQL Server Session State and have 3 web servers in a load balancer.

We have a Windows 2003 server running IIS6 1.1 Framework. We have also installed a DNS and Active Directory in the same machine.

We're randomly getting the error you can see below. Sometimes it causes the recycling of process w3wp.exe (which on my understanding represents the application pool worker processd) and other times results on this process hanging and not responding to any request. To do iisrest temporarly solves the problem.

We were pointed to a possible permissions problem between the user we were runnig the DefaultAppPool with and registry entries used by the iis. We noticed the default predifined user we used, Network Service, wasn't found in the Active Directory, so we changed it by the default configurable user, IWAM_MACHINE_NAME, which is under the IIS_WPG Active Directory Grupo, which, in theory has the correct permissions to run the application pool.

Well, none of this worked and we are still getting this error.

This is driving us crazy and think the problem might have to do with having the Domain Controller/Active Directory and the IIS6 running on the same machine. We'll try now uninstalling this DC pointing to another one to see what happens.
